Wireless Sensor Networks (WSNs) have a tremendous potential to improve the efficiency of many systems, for instance, in building automation and process control. Unfortunately, the current technology does not offer guaranteed energy efficiency and reliability for closed-loop stability. This paper is to provide a modeling, analysis and design framework for WSN protocols used in control applications. The protocols are designed to minimize the energy consumption of the network, while meeting reliability and delay requirements from the application layer. The design relies on the analytical modeling of the protocol behavior. First, modeling of the slotted random access scheme of the IEEE 802.15.4 Medium Access Control (MAC) is investigated.
